| Abstract | Multibeam data were collected with a portable ELAC BottomChart MkII system (Seabeam 1050), consisting of 50 kHz transducers/receivers which were mounted in the moonpool of the ship. A frequency of 50 kHz and a maximum opening angle of 120 degrees was chosen. The opening angle could then later be reduced to 100 or 80 degrees via the settings menu. Later an opening angle of 80 degrees was chosen, when surveying in water depths greater than 1000 m. The number of beams of the system is 129 with a beam angle of 1.5 degrees. The maximum water depth which can be mapped with this configuration is somewhere between 2000 m and 2500 m. The quality of the data strongly depends on weather conditions. Rough sea leads to the formation of bubbles underneath the ships hull and, therefore, reduced data quality. Fortunately the sea was very calm most of the time. |
